Electric motor 450 kW, 2985 rpm, 400 V / 690 V, 4LC-355LX2A-2 LV

High energy losses, excessive heating and unplanned downtime in heavy-duty operations tend to raise the costs of the entire line very quickly. The 4LC-355LX2A-2 model with an output of 450 kW is designed for applications where the drive operates in the speed range of 2900-3000 rpm and where long-term operation with high reliability and lower energy requirements is expected. It is a solution that helps reduce operating expenses without compromising output stability.

This low-voltage asynchronous electric motor uses a design for demanding industrial loads while also meeting the requirements for energy-efficient industrial motors. The shaft height of 355 mm provides a robust base for installation in technological assemblies where a strong mechanical connection and high operational discipline are required. The rated current at delta 400 V reaches 737 A and at star 690 V 427 A, which gives integrators a clear framework for power supply and protection design.

Operation in the 2900-3000 rpm range with low losses

In this speed class, the 2-pole electric motor operates at a rated speed of 2985 rpm, which is suitable for technologies requiring high speed and continuous output. An efficiency of 96.7 percent and a power factor of 0.91 support economical operation at high load, while a starting torque Tst/Tn of 1.6, a breakdown torque Tmax/Tn of 2.2 and a starting current Ist/In of 8.5 allow a more accurate assessment of behaviour during start-up and dynamic load changes.

Mechanical equipment for integration into large systems

The design includes cable glands 2-M63X1.5, DE 6319-C3 and NDE 6319-C3 bearings, and accessories in the form of 3 PTC thermistors. The packaging weight of 2100 kg reflects the robustness of the design and the need for careful handling during installation. Noise level 95 dB(A) is a parameter that must be considered when designing acoustic insulation or positioning the drive in a hall.

Use in demanding industrial operations

• Pump sets for high volume flow rates and continuous operation.
• Ventilation and blower systems with high demands for stable output.
• Compressor drives in technological units with continuous load.
• Conveyor lines for metallurgy, mining and materials handling.
• Mixing and processing equipment in the chemical and process industries.
• Auxiliary drives in power engineering and in large production blocks.
